When matching against custom window properties or atoms perform the
matching against all available values using logical OR if the special index
`[*]` is specified. If no index is specified, we fall-back to the first
value.
This should help when an atom has multiple values and you only want to
check against any of these — e.g. hiding windows with state `hidden`:
`--opacity-rule "0:_NET_WM_STATE@[*]:32a *= 'HIDDEN'"` — without having to
explicitly specify each index separately or when the index is not known
in advance.
Updated the manpage with examples for hidden and sticky windows.
Per POSIX, "The c argument is an int, the value of which the application
shall ensure is a character representable as an unsigned char or equal
to the value of the macro EOF. If the argument has any other value, the
behavior is undefined."

- Fix non-critical memory-leak in `picom.c` and `options.c` where we
don't free all allocated memory before dieing.
- Explicitly allocate new branch in `c2.c` to silence false-positive
memory-leak.
Of course, we still use GLX, so we can't completely remove Xlib yet. But
this removes all Xlib uses outside of the backends.
This drops support for COMPOUND_TEXT Xorg strings, so people how wants
multilingual support has to use UTF8, which should be fine since most of
the applications support that.

leftovers:
1) config file path. Has to implement compatibility functionalities before
we can change it.
2) links in man pages. Has to migrate the repo first.
3) _COMPTON_SHADOW, it has become a defacto standard, so we have to keep
supporting it.
4) dbus names, undecided whether we should/could change it.

Currently compton handles window creation event by immediately query all
the information it needs and create a window struct with that
information. However, this is prone to race conditions.
In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.
This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.

Window state tracking is basically the back bond of window fading. We
add a new enum field to the win struct to track the state of the window,
instead of using a set of boolean variables. We also remove the fading
callbacks, since it is only used for fading, so the potential of code
reuse is lost. And it makes the code slightly harder to understand.
Also fixed a problem that --no-fading-openclose is not behaving as
advertised (from my observation, enabling this flag disables fading
entirely, instead of just diabling it for open/close).
Also uses double for opacity everywhere internally. Use opacity_t only
when setting X opacity prop.

Slightly clean up header inclusion with the help of clang's module system.
It's better for files to include the things you need directly.

* Pass a options_t, not session_t
* Slightly improve error handling when setting vsync method via dbus
The goal here is to limit the scope of what a given function can access.
And session_t contains basically everything, so don't pass it around.

IANAL, but I think I am allowed to add missing copyright notices for
someone else. And I did my best job using git history to figure out who
wrote which functions. So I hope everything is fine.
Instead use win_has_alpha to check for alpha channel, window mode is
reserved for determine if the window is possibly transparent.

Add `bounding_shape` and `rounded_corners` as condition match target.
Deprecate --shadow-ignore-shaped. Add rounded-corners detection to
win_is_fullscreen(). Slightly modify win_rounded_corners() logic. Thanks
to tdryer for reporting. (#191)
- Try to avoid evaluating conditions after window unmap/destruction.
Unfortunately, frequently this doesn't work due to the asynchronous
nature of X.
- Add _GTK_FRAME_EXTENTS exclusion rules to compton.sample.conf. Thanks
to memeplex, hexchain, and others for info. (#189)
- Add debugging option --show-all-xerrors, and other debugging changes.
Doc update.
- Rewrite focus detection logic. Remove w->focused_real and use
ps->active_win to identify focused window uniformly. Use a more
expensive way to filter FocusIn/Out events to improve reliability.
Only limited tests are done, and bugs are likely to be introduced.
(#99)
- Known issue: Under fvwm, compton sometimes does not consistently
report the window input gets sent to. But there's something wrong in
that case: XGetInputFocus() shows the root window is focused but
another window is receiving input.
- Add stoppaint_force option, controlled via D-Bus, to stop painting
completely, which may look better than unredirecting the screen,
sometimes. (#41)
- Add x2, y2 matching targets.
- Update documentation.
